How to Grow and Care
Most Pelargoniums are grown in pots in a green house or conservatory. They can also be grown inside the house, but need to be in the most sunniest area possible. Many species do well when they are planted outside in an open area, so that they can become larger plants. This can be a problem though if you want to replant them in a pot for the winter months. Cuttings can be taken in the summer time instead to make new plants.
Succulent species grow well with other succulents and cacti. Pelargonium are very attractive and one of the toughest and most durable succulents.
